Question

In a step down transformer, the number of turns in the primary is always :

• A. greater than the number of turns in the secondary
• B. less than the number of turns in the secondary
• C. equal to the number of turns in the secondary
• D. either greater than or less than the number of turns in the secondary

Answer 1

The correct option is A greater than the number of turns in the secondary

In step down transformers, voltage in secondary coil decreases. and we know that

$\frac{E_s}{E_p}=\frac{n_s}{n_p}$
So, number of turns decreases in secondary coil with respect to primary coil.
